OF BROOKLYN, NEW YORK, A CORPORATION OF NEW YORK CONTAINER CLOSURE I Application filed February 25, 1932. Serial No. 595,001.

My invention relates to improvements in container closures and it is my object to provide a container cap of the reseal type which will combine strength, correct fitting on a container and present an attractive appearance in a better way than any cap now in use and in which the container contents cannot come into contact with any metal part of the cap.

My improved cap has the following advantages over the types of cap now in use z The cast, molded or machined threads, lugs or the like on the inner face of the filler within the cap which engage counterparts on the container to create and hold the sealing pressure on the gasket give a. better hold and allow wider tolerances in the dimensions of the container than is possible in the case of threads, lugs or the like formed from sheet metal. My cap offers all the advantages of a metal cap but no metal can come into contact with the container or the contents. My cap may be lithographed in colors and designs on the outside of the cap, is cheaper than the molded caps now in use and will not break if dropped or if applied to the containeir too tlghtly as by machine at high spee In the drawing I have shown variations of my cap which consists essentially in an outer shell, a filler and a sealing gasket. Fig. 1 is a sectional view of a preferred form of my cap; Fig. 2 a like view of a furthermodification; Fig. 3 a side view of a completed cap as shown in Fig. 1; and Fig. 4 a view of an applicator secured to the rigid plate and gasket shown in Fig. 2. v The cap comprises an outer shell of sheet material having a top 1 and depending side walls 2 of any desired length. This outer shell may be smooth and attractive in appearance and may be of any desired shape and decorated in any desired manner.

The filler 3 is formed of rigid. non-metallic, preferably impervious and chemically resistant, material. The outer periphery of this filler may be smooth and round or of any desired shape and finish. Its inner wall is provided with a thread, lugs or other means which engage counterpart means on the neck of the container to create and maintain the sealing pressure on the gasket.

The cap shown in Fig. 1 has a sealing gasket 4 therein extending over the inner, top surface. The filler 2 is placed therein and its upper edge bears against the gasket. As a means of holding the parts together the edge of. the shell is curled under a shoulder at 5 which firmly clamps the parts together. This form provides greater friction between the parts to prevent the filler and outer shell turning with respect to one another. The gasket is held more firmly in the cap and cannot fall out before application to the container and cannot stick to the top surface of the container after the cap is removed. This construction also insures a definite depth of the cap below the top sur face of the sealing gasket and obviates the necessity of compensating for variations in the thickness of the gaskets and makes possible a better fit between cap and container and permits greater tolerance in the dimensions of the container. Through the compression of the outer portion of the gasket, especially when one made of a very resilient materialis used, a central bulging of the .gasket'takes place through the compression against the top of the shell which forces it toward the inside of the container mouth, thus forming an inner seal as well as a top seal.

In the cap shown in Fig. 2 the outer shell has a domed top 1". A stifi disk 7 is located therein under the dome and the sealing gasket 4 lies against the under side of this stiff disk. The filler 3 is located below the gasket with its top edge bearing on the gasket. The edge of the shell may be curled over at 5 to hold the parts together.

If it is desired to secure an applicator, such as a dauber, brush, quill or rod, to the cap the applicator 8 may be secured to the stiff disk 7 and gasket 4 as indicated in Fig. 4 and inserted in the outer shell with the filler.

Any suitable means may be used to secure the parts together, the filler may be a force fit for the shell or cement may be used between the shell and filler to further bond the parts together if desired.

I do not limit myself to any particular length of depending side walls of the outer shell as any side wall long enough to engage the filler is within the scope of my invention.

My cap may be used for vacuum packing as well as the uses to which reseal caps are generally put.

I disclaim the use of metal in making the filler.

I claim 1. A container closure consisting of a rigid non-resilient, non-metallic tubular element open at both ends and having means whereby it may be attached to a container to close the same, a sealing gasket closing the top of said element, and a deformable shell of sheet material inclosing the top and the side of, and permanently secured to said element and inclosing said gasket and holding the same engaged with said element.

2. A container closure consisting ofa rigid non-resilient, non-metallic tubular element open at both ends and having interior means whereby it may be attached to a container to close the same, a sealing gasket extending across the open top of, and bearing upon the end of said tubular element, and a deformable shell of sheet material inclosing the top and the side of said element, and secured thereto in engaging relation with said gasket, whereby the edge of said gasket is compressed between said shell and said element.

3. A container closure consisting of a rigid non-resilient, non-metallic tubular element open at both ends having interior means whereby it may be attached to a container to close the same and an exterior shoulder, a sealing gasket extending across the open top of, and bearing upon the end of said tubular element, and a shell of deformable sheet material inclosing the top and the side of said element, and secured thereto in engaging relation with said gasket by having its lower edge formed below and in en aging relation with said shoulder, whereby tie edge of said gasket is compressed between said shell and said element.

1. A container closure consisting of a rigid non-resilient, non-metallic tubular element open at both ends, having interior means whereby it may be attached to a container to close the same, a sealing gasket extending across the open top of, and bearing upon the end of said tubular element, a shell having a domed top of deformable sheet material inclosing the top and the side of said element, and secured thereto in engaging relation with said gasket, whereby the edge of said gasket is compressed between said shell and said element, and a stiff disk interposed between said gasket and the top of said shell.

In testimony whereof, I have aflixed my signature.

JESSE GUTMANN.
